Ppc uartd

The ppc_uartd daemon is a Buffalo-specific daemon; it kicks the external
hardware watchdog regularly. It is the stock avr_evtd daemon and monitors the buttons, the
fan and how full the hdd is. If it isn't running, the slave microcontroller will assume
a hardware or software failure and power down the system.

avr_evtd is the opensource variant and was created by Lb worm using kuro_evtd-source as a base.
